Ohhh...so thats a scalloped look...guess I was way off on that one.transform and rotate a small circle the radius of the desired scallop
weld them all together
break apart the welded shape
the inner circle is the scalloped one.
You can also do a back minus front if you prefer///
Now THAT is cool! The overlooked polygon tool is one that I've more than once seen used in imaginative ways. Good thinking and thanks for posting. - Scottyanother fun way is to use the polygon tool....
Use the CTRL to draw a perfect polygon, then set the # of sides to something you like (say, 20-25)
Then delete the deeper node (it affects all of them)
Then select the line segment and convert it to a curve segment
Then use the node tool to select the curve segment in the middle and drag it wherever you want.
